To address the issue, we need to validate the response.id field before using it to access this.pendingMessages. Specifically:
- Check if
response.idexists as a key inthis.pendingMessagesusingObject.prototype.hasOwnProperty.call. - Ensure that the value associated with
response.idinthis.pendingMessagesis a function before invoking it.
This fix ensures that only valid and expected keys are used for dynamic method calls, mitigating the risk of runtime exceptions or unexpected behavior.

no need to review this just yet; mostly just opening this for visibility. adds an alternate auth client that proxies cloud requests to the parent frame. in the future, i'll swap out the frame implementation with one that talks over the IPC channel to minecraft
